Systems for levitating a metallic tray

Abstract

A system for processing solar cells is disclosed which includes a separation module for separating a processing frame from solar cells that are fed along a conveyance line. The processing frame can be separated without requiring manual lifting of the processing frame by feeding the processing frame and solar cells into a magnetic roller system. The magnetic roller system can gradually lift the processing frame away from the solar cells and divert the processing frame to a separate roller system. The solar cells can remain on the main conveyance line for further processing.

What is claimed is: 
     
       1. A system for processing solar cells, the system comprising:
 a roller frame comprising a first frame portion a second frame portion; 
 a plurality of rollers arranged between and along the first frame portion and the second frame portion, the plurality of rollers for transferring a processing frame and a plurality of solar cells arranged within the processing frame, the plurality of rollers comprising:
 a plurality of lower rollers; 
 a plurality of upper rollers arranged above a first portion of the plurality of lower rollers; 
 a plurality of magnetic rollers arranged above a second portion of the plurality of lower rollers and adjacent to the plurality of upper rollers; and 
 a plurality of separation rollers arranged above a third portion of the plurality of lower rollers and below a portion of the plurality of magnetic rollers. 
 
 
     
     
       2. The system of  claim 1 , wherein the plurality of lower rollers and the plurality of upper rollers transfer the processing frame between them. 
     
     
       3. The system of  claim 2 , wherein the plurality of magnetic rollers are arranged to incrementally increase in distance from the lower rollers for lifting the processing frame off of the lower rollers, and thereby separating the processing frame from the solar cells. 
     
     
       4. The system of  claim 3 , wherein the plurality of lower rollers are arranged to carry the separated plurality of solar cells underneath the plurality of separation rollers. 
     
     
       5. The system of  claim 4 , wherein the separation rollers are arranged to receive the processing frame after it has been separated from the plurality of solar cells. 
     
     
       6. The system of  claim 1 , further comprising rinsing devices arranged above the upper rollers for rinsing the processing frame and plurality of solar cells. 
     
     
       7. The system of  claim 1 , wherein each first and second frame portion carries a plurality of gears for driving the plurality of rollers.
